Positive Hall effect in paramagnetic amorphous Zr-Fe.

Abstract

We present measurements and analysis of the Hall effect in amorphous paramagnetic Zr-Fe. From the correlation between the Hall coefficient and the valence susceptibility we show that the Hall effect is dominated by an anomalous contribution due to the side-jump effect, the first time such a contribution has been clearly identified in an amorphous paramagnetic system. We propose that the anomalous contribution accounts for the positive value of the Hall coefficient seen in many amorphous alloys.
